PEG/PPG-10/70 COPOLYMER.

Valuable CAS 9003-11-6 (generic) / SOLVENT

A synthetic polymer, PEG/PPG-10/70 Copolymer functions as a sophisticated skin conditioning agent and humectant, enhancing the sensory profile and hydration of formulations. Its balanced polyethylene glycol and polypropylene glycol structure allows for a unique interaction with the skin's surface.

Summary

Skin Conditioning Agent Humectant Emollient

Science

Mechanism of Action

This copolymer operates by forming a flexible, non-occlusive film on the skin, which efficiently attracts and retains moisture within the stratum corneum. The polyethylene glycol (PEG) segments provide humectancy, drawing water to the skin, while the polypropylene glycol (PPG) segments contribute to emollience, ensuring a smooth, non-tacky finish that optimizes skin feel and supports barrier function.
